Possibly the contrast dial on the back is turned down? I bumped mine and thought it was not working and the contrast was just too low to see. Attached is my config file, but take it with a grain of salt. Some things have change -- you can change eprom settings directly with Repetier-Host. And I rerouted my power for D10 to D9. And my arm length is 272mm--wanted maximum bed reach. Hopefully itby rtideas - Delta Machines
Pulled a couple all nighters getting my printer working over the past couple weeks. Rebuilt the head twice. Flashed the firmware so many times now I might be on an offenders list. Tried all stable and all beta versions of slicers I could find. Getting to know Sketchup on a much more personal level. And lost 4-5 lbs. Sucked in making it work--forgot to eat, sleep and drink. So far, I'd call it aby rtideas - Delta Machines
Quoteibonneau Hey guys, Just a quick question, thinking of buying this kit when I come for a visit late in March to the US. anyone can tell me the weight of the package and dimensions - Need to see if I can fit it in my luggage. Thx p.s. tried calling and writing the Folger guys but no answer as of yet. My box was 32" x 10" x 7" and guessing about 16-20 lbs. Folgertech's customer service isby rtideas - Delta Machines
Closer. Got the servo to work at least. Figured out the wiring from this: Here is a closeup of mine: Since my drill bit had pilot hole tip and didn't allow for a tight fit, I added a set screw on the side so I could adjust the arm on the servo. Also, not certain where the servo would rotate to once turned on. Most other Kossels with this switch set up pop of the roller arm for the switch. Sinby rtideas - Delta Machines

My extruder to moving about 4x the distance it is supposed to. telling it to move 10mm, actually moves about 38.5mm of filament." With the folger tech extruder and 1/16 microstepping.

I did see they added new Z-probe manual and Autolevel firmware on one of their Google Drives: https://drive.google.com/drive/#folders/0B_KUgGb2XPIXYnBmdHMxOUFBazQ But i'd be very careful homing the head with their firmware. Haven't tested it just yet. The last one I tried from them tried to crash my head. Glad my hot bed was not installed yet and was able to hit the kill motors button in time.by rtideas - Delta Machines

Quoteiceman62 Are you getting anything to work in the Repetier FW like Auto Leveling or the LCD cause I could not get either to work under Repetier FW. I'm using 0.92 Repetier firmware. The X and Y direction were swapped. I swapped the X- and Y-motor and the X- and Y-stop wiring. BUT I could have just swapped the angles for the columns--210 with 330 and vice versa.

Anyone getting decent results with the included 36T pulleys? I got 20T ones that I'm thinking of using instead.by rtideas - Delta Machines
Iceman62, Oh. I see it is Marlin firmware. I've been using Repetier. Going to try a few more things with Repetier, first.by rtideas - Delta Machines
Excellent! Thank you. Unfortunately, ill be gone for a week, so have to wait to try it.by rtideas - Delta Machines
Quoteiceman62 you just want a copy of the Arduiono Sketch? Yes please. Want to compare my settings to see what's inverting the X. Just the Configuration.h from the Repetier set up what I need.by rtideas - Delta Machines
Quoteiceman62 Thank You!!!! I tried that and it started the print and printed a beautiful little bird's nest. I don't have it set to go all the way down to the hot bed yet I still have to get that part figured out. But just to actually see it do something was exciting. Again unnokeng Thank you so much for your help.... Congrats! Care to share your configuration file for your firmware set up?by rtideas - Delta Machines
Quotednguyenai598 Endstop in reverse? You are off by one at the header; there are six inputs into that header, every other three are minimum endstops and every other three are maximum endstops, you want the maximum endstops. There should be a pic in the doc. It was these settings I had to set to 1 and now my endstops work properly: #define INVERT_X_DIR 1 #define INVERT_Y_DIR 1 #define INVERT_Zby rtideas - Delta Machines
Quotedougal1957 Glad to help. I couldn't get marlin to even compile for me hence I went to Repetier which to be honest I prefer anyway now though next printer will be a 32 bit controller as it will be a semi large delta (400mm dia bed with 1000mm towers) should give me about 550 mm build height at 350mm diameter or so just need to print all the parts for it now.

Quotedougal1957 You do have the 3 jumper fitted underneath all the Stepper driver modules don't you? Yes. All jumpers in place and configuration set to 44.44 mm/step.

Closer. At least it's moving. Installed 0.91 Repetier firmware. I matched all the settings to the configuration file in the FolgerTech Google Drive except for rod length and my added LCD screen. Googe Drive--FolgerTech Kossel 2020 software package.zip. The printer moves, but 0.1 mm steps are giant at 6 mm. 1mm are 60 mm. 10 mm are 600 -- I don't dare. Using the 36 tooth pulleys.

Trying to use what came with the kit. Was missing the 30mm tensioner bolts listed in the Build Manual. After searching my local hardware store (limited metric), Lowe's (too short), my favorite hobby shop, another hardware store recommended by the hobby shop (same selection as Lowe's), I found the bolts at another hobby shop across town. They manual should recommend 35mm or longer. Also, the nyloby rtideas - Delta Machines
And once again, coming up short with this kit. The leads for the hot end are too short. Grrrrrr. What gauge wire do I need to add extensions to the hot end heater wires? Needs about a 25-30cm more of wire. Already had to make extended leads for the fan.by rtideas - Delta Machines
The acrylic parts are definitely beta. One of the hot bed mounting pieces was missing a hole completely. Any piece that needed to be attached to the frame with t-nuts and the suggested M3x8 screwed barely got a thread to catch. I Dremeled them out so they could get a better bite. First I used a ball shaped reaming tool. Then a flat toothed disc to allow the screw to inset a millimeter or two.by rtideas - Delta Machines
Anyone figure out what the lock washers are used for? What is the consensus on the rod length to cover the full heated bed? What's the set up for the top belt pulleys? The photo shows two flanged bearing and two washers. The text states two flanged bearings and one normal bearing between them. Seems to have a bit of slop. Are you using the supplied gear for the belt motors? I saw someone triedby rtideas - Delta Machines

Quoteunnokeng Before I go, I saw a mistake on the instructions manual for the build. I had originally built my effector rods longer, but decided to redo it and follow the instructions. Well, it was wrong! It tells you that the rods should be at 224mm. With this whole kit scaled up, it will only give you an effective build diameter of 150mm. I already ordered some replacement rods so I can mby rtideas - Delta Machines
Be sure to check your filament path for schmutz as well. Saw these particles looking into the Bowden tube end on the hot end. Pushing the teflon tube into it may help clear it, but still waiting on parts before building more. Will also gently polish my nozzle. Discovered more missing parts from my kit. Fan, a bunch of screws, and auto-leveler parts. Still have not heard back from support at Fby rtideas - Delta Machines
Yay! My kit arrived today From Folger Tech. Boo. It is missing the additional LCD display controller I ordered from them, and the acrylic set shown in the Build Manual. The kit looks decent enough. Just will have to wait (again) for the missing parts. Hopefully they will get back to me quickly. It does say Kossel Kit Rev A beta, so they may still have a few kinks in their system.

dnguyenai598, LOL. Yes a blessing. And thanks for the pic. Drool. Good to see they are shipping. I did print out a drawing of a Kossel to scaled to 700mm tall, on multiple sheets of paper taped together to roughly see how big it will be on my desk. The real thing will be there soon enough.
